Introduction to JavaScript

Duration: 3 Days

Description

This 3-day course introduces participants to the core concepts of JavaScript for front-end web development. It covers language fundamentals, event handling, forms, DOM manipulation, and debugging, along with modern JavaScript features like arrow functions, destructuring, and array methods. Through hands-on practice and a capstone project, attendees gain practical skills to build dynamic, interactive web pages using JavaScript.

Audience

This course is designed for aspiring front-end developers, designers, and QA professionals looking to add JavaScript to their skill set. It’s ideal for those with basic HTML and CSS knowledge who want to start programming client-side functionality; no prior JavaScript experience is required.

Objectives

  • Write and debug JavaScript code using modern syntax
  • Use variables, functions, loops, and conditionals to control program logic
  • Create and manipulate JavaScript objects and arrays
  • Handle user events and validate form inputs
  • Access and modify the DOM dynamically
  • User regular expressions for basic pattern matching
  • Understand scoping, closures, and modern ES6+ features

Prerequisites

Participants should have a basic understanding of HTML and CSS, including how to structure a web page and apply styles. Comfort with using a text editor and web browser developer tools is expected. No prior programming experience is necessary, though familiarity with general computing concepts will be helpful.
